Filed Dec. 22, 1% Ser. No. 161,461 2 Claims. (Cl. 1523-452) This invention relates to a pump for transferring liquid from one area to another and more particularly concerns a pump ewecially adapted for transferring gasoline from the tank of one vehicle to the tank or" another vehicle.

According to the invention there is provided a bellowslike casing provided with handles which can be worke to expand and contract the casing. *Inlet and outlet tubes are connected to the casing and are provided with oneway valves pennitting liquid to enter the casing through the inlet and to leave the casing through the outlet. in a modification of the invention, a motor is provided for expanding and contracting the casing to draw in liquid and to drive liquid therefrom.

it is therefore one object of the invention to provide a pump which is manually actuated for transferring liquids therethrough.

A further object is to provide a liquid transfer pump including an expansible casing and an electric motor for expanding the casing.

For further comprehesion of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims which the various novel features of the invention are more particularly set for h.

FIG. 6 is a sectional View on an enlarged scale taken on line 6-6 of FIG. 5.

FIG. 7 is an end View of the pump of FIGS. 5 and 6.

FIG. 8 is a view similar to FIG. 2 of a pump embodying a further modified form of the invention.

Referring to FIGS. 1 and 2, there is shown a fieidble bellows-like casing 10 which is V'shaped in cross section. The opposite ends 12 and top 14 define gussets permitting expansion and contraction of the casin The sides of the casing are open md formed with rectangular channels 16 in which are fitted edges of rigid metal or plastic plates 13, 18. Each plate 18 and 18', as clearly shown in FIGS. 1-3, has a peripheral bead 2-4 which fits snugly into the channel :16 at each side of the casing. Each of the plates 13, 3' has a hole 21, 21 near its bottom edge. A valve assembly 22. has a core 23 screwed into hole 21. This core has an axial passage 25 term-inating at a seat 24- against which a ball 2:? is pressed by a coil spring 28 in the core. The core has lateral holes 29 which open into a cylindrical bore 36 formed in a valve housing 32 in which the core is screwed. A flexible tube 34 is attached to the end of housing 32 and serves as an outlet tube for liquid which may fill the casing.

In hole 21 of the other plate 13 is screwed a valve core 36 of another valve assembly 3 5. A ball 49 is freely and mov-abiy disposed .in bore 42 in the core and is pressed on its seat by a coil spring 4-1. The core has lateral slits or holes 44- comrnunicat-ing with the bore 42 and with the interior of the casing. A plug 45 closes the end of bore 42 to hold the spring and ball in the core. The core has a central passage 43 communicating with the axial bore 4.3. A seat 46 :is defined at the inner end of bore 42 at passage .-3 against which the ball can be pressed to close the passage. A valve housing 48 is threaded on core 36. On this cylindrical housing 4-3 is fitted a flexible tube 56. The tube serves as an inlet pipe or conduit for passing fluid into the casing.

Handle bars 52. are welded or otherwise secured to plates i8, 13 at opposite sides of the casing. These bars extend u warly to form handles 54 on which may be disposed hand grips 56. A leaf spring 6% is disposed in the casing with apex 67 abutting the apical bottom end 15 of the casing. Rivets 62 extend through aligned holes 63 in the spring and plates and secure the spring to plates 18, 18. Spring plate '69 may have external grooves 64- in which are received beaded portions l7 of the chamiel 16 engaging the beads 23* of the plates l8, 18'. As shown best in FIGS. 2 and 4, the spring plate 6i. has holes 65 in opposite sides through which the openings in the valve cores 2.3, '26 are exposed. the spring plate may be formed to assume a general V- shaped as shown in B653. 2 and 4, so that some force must be exerted to bring the sides of the spring together. Altemately, the spring plate may have its sides substatitially juxtaposed so that force must be exerted to separate them.

In the embodiment of FIGS. 1 and 2, the sides of the plate 65' are normally spread apart and the casing 19 is in an expanded condition. When the handles are brought together against tension in the apex 67 of the spring 69, the casing is contracted. it, upon such contraction, the free end of tube 543 is inserted in a gasoline tank of one vehicle such as an automobile and if the free end of tube 34 is inserted into another tank or container, the contents of the first-trained tank will be drawn by suction through valve assembly 35 into the casing 19 and when the casing is expanded the contents of the filled casing will be expelled through the one way valve assembly 22 into outlet 34- to the other tank, container or receptacle therefor. Valve 22 closes when valve 35 opens and vice versa.

If desired, spring 59 may be omitted, since the handles 54 may be worked to expand and contract the casing Without assistance of the spring in expansion and opposition of the spring in contraction.

In FIGS. 57 there is shown another form of the invention, in which parts corresponding to those of PlGS. 1-4 are identically numbered. A motor 62 mounted on a base 64' has a shaft 65 which passes through a packing sleeve 63 in the end wall 12 of the casing. An elliptical roller 71 is axially mounted on the shaft between the sides of leaf spring plate 6%. lhe spring plate is formed so that its sides are normally close together. The roller, during rotation, serves to separate or spread the sides of the spring 6% when the rollers major axis is horizontal, as shown by the solid line position or" the roller in FIG. 6.

When the minor axis of the roller is horizontal, as shown by the dotted line position of the roller in FIG. 6, the spring contracts and the casing contracts also. The motor thus serves to expand the casing to establish a suction therein and liquid then enters the casing through valved inlet 59. When the spring 60 contracts, the casing contracts and the liquid in the casing is expelled through the valved outlet tube 34.

A handle 72 is provided for carrying the device. The

motor has a power cable 74 which terminates in a plug 75 for connection to an external power supply, either a convenience outlet or to a suitable socket or receptacle 3 connected to the battery or cigarette lighter of an automobile or other vehicle.

Referring now to the modified form of pump'80 illustrated in FIG. 8, this is a motor operated pump somewhat similar to the pump of FIGS. 5 to 7, inclusive. In pump 80, however, an auxiliary flexible plastic casing 82 is provided in the interior bottom of the main casing The auxiliary inner casing 82 is defined by a top 84 and by the ends 12 and bottom 15 of the main cas ing 10 and by the sides of the spring plate In main casing 1d, the side plates 18 13 are formed with holes 21 21, respectively, midway the ends thereof, and projecting radially from said openings are integral tubular bearing members 23 and 36 communicating with the holes in the plates and with the interior of the main casing. The end of a plastic supply hose 5% is sleeved around the bearing member 36*, and the end of a discharge hose 34 is sleeved around the bearing member 23*.

The end of the supply hose 5!? is equipped with a pivoted valve plate 86 normally engaging a shouldered seat 83 in the end of the hose and sealing oil the inlet end of the hose. Upon expansion of the casing 10*, however, the vacuum together with the force of the liquid force the valve plate 86 oiT of its seat permitting the liquid to flow therearound and into the main casing it, the top 82 of the auxiliary casing preventing the liquid from flowing into the auxiliary casing. A similar pivoted valve plate 90 is mounted in the end of the outlet hose 34 normally engaging a shouldered seat 92 therein. Upon contraction of the casing 10 the force of the liquid therein will move the valve plate 90 oil of its seat 92 permitting the liquid to flow through the outlet hose 34- to its destination. I

The contraction and expansion of the casing 10* is accomplished by means of a substantially rectangular-shaped roller having rounded ends 94 fixed on the bifurcated end of a vertically disposed shaft 66 of a motor 62* supported on upstanding brackets 96 formed integrally with the bottom ends of the sides of the spring plate 6th. The pump 89 is supported in upright position on the base 64 by means of a bolt and nut assembly including bolts 98 and nuts 99.

In all other respects, the pump is similar to the pump of FIGS. 5 to 7, inclusive, and similar numerals are used to indicate similar parts.

The pump 80 operates similarly .to the pump 10 of FIGS. 5 to 7, inclusive, that is, the spring plate 60 is formed so that its sides are normally closed together thereby drawing the sides of the main casing 10* close together. The roller 70 during rotation serves to separate or spread the sides of the spring and sides of the main casing 10*. When the'minor axis of the roller is horizontal, the spring 60* contracts and the main casing 19 contracts also. The motor thus serves to expand the casing 10 to establish a suction therein and liquid then enters the casing through the bore in inlet bearing member 36*. When the spring 60 contracts, the casing 10 contracts and the liquid in the casing is expelled through the valve outlet tube 34*, 4

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
